1. Fitting the pion and kaon mass and decay constant to lattice data
University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationAbstract : We use lattice QCD data to perform a fit of the pion and kaon mass and decay constant to next-to-next-to-leading order (NNLO) in three-flavor Chiral Perturbation Theory (ChPT). To improve our fits, we make use of finite volume corrections at both one- and two-loop order. This turns out to provide a small but noticeable improvement of our fits. READ MORE

2. Simulation of Higgs boson pair production in Vector Boson Fusion at the LHC
University essay from Uppsala universitet/HögenergifysikAbstract : MadGraph5 is used to generate events with Higgs boson pairs from vector boson fusion (VBF) at leading-order (LO) and next-to-leading-order (NLO) accuracy in QCD. The simulations are used to compute fiducial cross-sections in proton-proton collisions at a centre-of-mass energy of 13 TeV, using several kinematic cuts on the outgoing jets, e.g. READ MORE

3. Flavour-ordering in the nonlinear sigma model with more derivatives and legs
University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisationAbstract : We present a generalisation of the flavour-ordering method applied to the chiral nonlinear sigma model with any number of flavours. We use an extended Lagrangian with terms containing any number of derivatives, organised in a power-counting hierarchy. READ MORE

4. Generation and Validation of di-Higgs events in the 4τ final state
University essay from Uppsala universitet/HögenergifysikAbstract : The Higgs self-coupling has a vital role by giving a deeper understanding of the Higgs particle. Furthermore, the way it opens to physics beyond the SM, encourages us to do MC simulationstudies for varying λ_hhh . READ MORE

5. Trigger Algorithms and Monte Carlo Event Generation for Dijet Searches in ATLAS and Beyond
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysikAbstract : So far, the Standard Model (SM) has been very successful in describing non-gravitational interactions of fundamental particles. However, many of its theoretical and experimental shortcomings remain unresolved. READ MORE
